Subject: [PATCH 1/6] Suspend: Fix compilation warning for CONFIG_SUSPEND unset

Suspend: Make debug facility depend on CONFIG_SUSPEND

Make the new suspend debug facility code depend on CONFIG_SUSPEND,
as appropriate, to remove the compiler warning printed when CONFIG_PM is set
and CONFIG_SUSPEND is not set.
